Dynamic Load Allowance Clause Samples
Dynamic Load Allowance. (DLA)
1. The Trackway vehicle vertical live load shall include a dynamic load allowance. The dynamic load allowance shall be used as DLA for the purpose of CAN/CSA S6, and shall have at least the following magnitudes, unless it is demonstrated in the Accepted ▇▇▇▇▇ ▇▇▇▇▇▇ OMF Building Parametric Programming Report or the Accepted ▇▇▇▇▇ Farms Storage Facility Building Parametric Programming Report, that a modified DLA is appropriate to use in the design of Maintenance and Storage Facilities:
a. For global effects = 2.16 ― 0.2 ― 0.27, but 0 ≤ ≤ 1, where is according to Table 6.2 in EC1 (in metres). If is not specified in Table 6.2 in EC1, shall be taken equal to the length of the influence line for deflection of the component being considered;
b. For local effects due to loading from one bogie - = 1.00; and
c. For slabs on grade supporting direct fixation or embedded track - = 1.00.
2. DLA does not need to be included for the Trackway vehicle horizontal live loads.
Dynamic Load Allowance. (DLA)
1. The On-track Vehicle vertical live load shall include a dynamic load allowance. The dynamic load allowance shall be used as DLA for the purpose of CAN/CSA S6, and shall have at least the following magnitudes:
a. For global effects DLA = 2.16 — 0.27, but 0≤ DLA≤ 1, where LΦ is according to Table 6.2 in EC1 (in metres). If LΦ is not specified in Table 6.2 in EC1, LΦ shall be taken equal to the length of the influence line for deflection of the component being considered;
b. For local effects due to loading from one bogie - DLA = 1.00; and
c. For slabs on grade supporting direct fixation or embedded track - DLA= 1.00.
2. DLA does not need to be included for the On-track Vehicle horizontal live loads.
